MASTER WARNING ACTIVE variables missing, cannot read state

Trying to read the state of MASTER WARNING ACTIVE (and caution) for use in hardware lights, but for some reason I simply cannot access the variables. I cannot find any documentation citing the correct variable referencing. Is it A,H,L or some other type of variable? Any other variable available turns out as 0, no matter what the state is.

Currently using Axis and Ohs to collect data for display on Streamdeck. Is there a known way to access this information? Or is this part of the system bugged?

Any chance this works?

(L:Generic_Master_Warning_Active)

I had tested it before, and it did not work.
But appending a comma makes it work. The variable name thus looks like this:

Generic_Master_Warning_Active,

The same applies to master caution.
Can’t say it makes sense to me, but now its lighting up as it should. Bug?

Perhaps it’s expecting an argument value and requires the comma for syntax?

I found and copied that variable string straight from Mobiflight’s Hubhop website, so it’s possible it is wrong there and no one has noticed yet.
